" For conceptual models to be the shared property of a research community the concepts they involve must be capable of being shared. That is the case when a consensual understanding of these concepts has been achieved or can be achieved by means of definition, examples, etc . With respect to what is shown by a conceptual model there are differences at least with respect to computer science, mathematics and logic. Mathematical models in one way or another establish a functional cohesion between entities such as input values and output values. Logical models establish an interpretation relationship between formulae and structures. Models in Computer Science are largely organizational in that they show how data, a cooperation between agents, the process of creating a response to an external stimulus, an algorithm, or similar is structured. The emphasis of organization that is apparent in many models of computer science appears to be a consequence of either of the following: (1) complexity issues need to be dealt with such that a functional cohesion actually can be evaluated. Health Magazine Man Model (2) a domain of individuals or universe of discourse has to be established and the individuals within that domain are supposed to be capable of being distinguished from each other by means of their condition in that organization or particular handles available to a user of that model.

" One should not miss out the point that the original as well must be constituted in some way so it becomes accessible to the modeling individual I. IV. The term model is used in many communities with quite different traditions, commonly perceived problems, and purposes. To use the term properly therefore requires it being put into the right context. While this entry attempts to provide a general framework for talking about models it is not very likely that all communities would accept and use that framework. V. References [1] Stachowiak, H.
